Is Pearlshipping more like Ash showing interest in Dawn?

That's why I find Pearlshipping to be strong, the bond between Ash and Dawn feels natural.

Amour seems to be a gender reversed Pearl in some aspects. Serena wants and seeks Ash's attention and approval for things. Ash wants Dawn's attention and approval. Dawn is definitely someone important in Ash's life, she is the most important girl in his life. Ash's battling styles emulated Dawn's style. That's why if he were to feel like himself again, Dawn must physically be by his side. Compared to Serena, Ash is the most important male in her life, she wants to take over Dawn's role, the most important girl in Ash's life. Yet she doesn't seem to have made an impact on him, she isn't a battler like Dawn is and whenever she does battle, she emulated Ash's style. Hence Ash acts and behaves naturally around Dawn yet I feel there's some distance between Ash and Serena. Ash isn't sure how to act around her, when he gave her the ribbon while scratching his nose. It's also strange in a way, Ash wants to act more naturally around his 'old acquainted' friend but Serena ends up being so shy and surprised by Ash's friendly gesture that she hesitates, even though she wished for it.

This is why Dawn has to return at the end of XYZ if Serena ends up going to Kanto with Ash. It'd be like the unmovable object vs the unstoppable object. This is why there is without a doubt in my mind, my suspicions will be proven right. The parallels and differences between Dawn and Serena, Pearl and Amour are more apparent. Remember Tomioka had a hand in this to set up the next stage of Ash's journey.

Dawn has what Serena needs, her way of establishing a bond with Ash and Dawn's creativity in regards to contest moves and clothing designs. Serena has what Dawn needs, the awareness of her romantic spark and feelings towards Ash. It seems to me that Serena is more discerning about clothing, something that Dawn might need as she tends to reject a lot of her designs. Dawn is a confident person who picks herself up by the bootstraps while Serena is more of an inward-thinking, self-reflecting person. This is also why I feel their personalities were planned for Sun and Moon years beforehand, they share similar names relating to them, and act as though in accordance with these celestial bodies.

Ash has never really thought strongly about a girl before and after. Dawn literally changed his life so much that whenever she wasn't around, he was struggling. Ash-Greninja didn't count because he was almost neglecting most of his other Pokémon aside from Pikachu.

Also, don't forget that when Dawn and Ash had their battle in Unova at Cynthia's house. They ended up with a draw which shows how strong Dawn has become and how she is as a character. That show's how Ash and Dawn where so passionate with each other at training (Dawn was his partner at training Ash's Pokémon) and when they used to tag battle together (one of the greatest tag battles was in Pokémon movie Arceus and the jewel of life).

Unlike Dawn, Serena has skills as a performer (not as coordinator) she isn't used to battles. If she manages to work out in battling style (which i doubt it) she has a lot of work to do (starting about from zero). The only experience she has is from Ash's battles and only used this experience once (in XYZ episode 22). Serena doesn't train whith Ash, like Dawn did, and they didn't had together their own signature to show their bond.
Also, Don't forget that Serena in the mirror world supposed to be more powerfull than the normal Serena and concerned more in battles but although Ash one shot her Fenekin (imagine what normal Serena's Fenekin would have happend in that battle)

Even in High touch we can see how close is Ash to Dawn.

So if Mirror Serena is a Tsundere
Yandere Serena Confirmed!
